Place the high-frequency capacitor as close as possible to the pin. • You can minimize the power supply current dissipation due to the internal logic indetermination by making the clock to 4CLK or higher. ■ ORDERING INFORMATION Part number MB40C360PFV 6 Package 24-pin Plastic SSOP (FPT-24P-M03) Remark MB40C360 ■ PACKAGE DIMENSION 24-pin Plastic SSOP (FPT-24P-M03) +0.20 * 7.75±0.10(.305±.004) 1.25 –0.10 +.008 .049 –.004 0.10(.004) * 5.60±0.10 INDEX 0.65±0.12(.0256±.0047) 7.15(.281)REF C 1994 FUJITSU LIMITED F24018S-2C-2 (.220±.004) +0.10 0.22 –0.05 +.004 .009 –.002 7.60±0.20 (.299±.008) "A" 6.60(.260) NOM +0.05 0.15 –0.02 +.002 .006 –.001 Details of "A" part 0.10±0.10(.004±.004) (STAND OFF) 0 10° 0.50±0.20 (.020±.008) Dimensions in mm (inches). 7 MB40C360 FUJITSU LIMITED For further information please contact: Japan FUJITSU LIMITED Corporate Global Business Support Division Electronic Devices KAWASAKI PLANT, 4-1-1, Kamikodanaka Nakahara-ku, Kawasaki-shi Kanagawa 211-8588, Japan Tel: 81(44) 754-3763 Fax: 81(44) 754-3329 http://www.fujitsu.co.jp/ North and South America FUJITSU MICROELECTRONICS, INC.
